I loved photographing birds, it's quite a challenge because they won't sit still for you. A lot of them see the camera lens as a giant predatory eye, as soon as you point at them they're gone.
It's even more of a challenge when you can't afford to spend thousands of dollars on expensive lenses, and all of my best photos came about through luck rather than planning. Under a forest canopy is very low light, you're using a long lens because you can't get close to the birds, and you need a fast shutter speed to help account for camera wobble. it's not easy but a lot of very relaxing fun.
Mostly. When I was tracking those fairy wrens I was totally focused on them and not paying enough attention to everything else around me, and I got swooped by a Whistling Kite. I was standing underneath it's nest.
I dove into some bushes and wiped the sweat from my brow, then discovered it wasn't sweat, it was blood. That kite had struck me but I never felt it, 3 neat slices in my scalp.
@Luca The bird on the left in your post is exactly the critters I was trying to photograph, I never got as good a shot as the one you posted though.
